Getting Started

These instructions will guide you on how to execute the code on your local machine for development and testing purposes.

Prerequisites

You need to have the following packages installed:

  • Python 3.7+
  • PyTorch 1.9.0+
  • numpy
  • pandas
  • sklearn
  • wandb
  • torchvision
  • PIL

You can install these packages using pip:

pip install torch torchvision numpy pandas sklearn wandb pillow

Configuration

To run the program, you need to have a configuration file (config.json). Here is a sample configuration file that you can use:

{
    "learning_rate": 0.0001,
    "momentum": 0.9,
    "epochs": 50,
    "batch_size": 64,
    "augmentation_in_training": false,
    "model": "kimianet",
    "pretrained": false,
    "kimianet_weight_path": "../kimianet_weights/KimiaNetPyTorchWeights.pth",
    "dataframe_root": "/isilon/datasets/camelyon17/",
    "trail_sites": ["center_0", "center_1", "center_2", "center_3", "center_4"],
    "holdout_trial_site": "center_0",
    "font_path": "/usr/share/fonts/type1/gsfonts/c059016l.pfb",
    "train_val_portions": [70,10]
}

Note: Please adjust the parameters according to your needs and availability of computational resources.

Running the code

To run the code, simply execute the main Python script:

python main.py

The script will then start training the model according to the parameters specified in the config.json file.

The model weights will be saved in the current directory with a name specified by the parameters in the config.json file.
